CARBONATOR Filed Mar'ch 9, 1929 2 Sheets-Shee't Patented June 7, 1932 y UNITED s'rA'rEs PATENT oFFicE JAMESVKANTOR, OF .CHICAGQ ILLNOIS, ASSIGNOR' T LIQUID CARBONIC CORPORA- 4 TION, OF CHICAGO, ILLINOIS, A CORPORATION OF DELAWARE cARBoNA'roR Application filed March 9,

My invention relates to improvements in apparatus for saturating and partially saturating water with carbon-dioxide gas to produce what is commonly known in the commercial art as carbonated water.

It has for one of its objects, the construction of a carbonator which may be embodied in a small structure adapted to occupy a minimum of fioor space; which may be simply and cheaply manufactured and operated; which will be quiet in its operation and which will be entirely automatic.

Another object of my invention is to provide a carbonator in which the present type of carbonator body or cylinder maybe dispensed with. According to the present commercial practices the carbonator body is formed of cast iron, cast steel or the like, and due lto the fact that this material is readily attacked by water and by the carbondioxide gas, the tank or carbonator is lined with tin. One of the objections to a tin lined tank is, not only that'itv is expensive, but if the lining by any chance has a small pin hole or blow hole therein the carbondioxide gas will attack the lining at this point and due to the frequent Achanges of pressure within the carbonator body will tend to loosen the lining until its effectiveness has been destroyed. i

My present type of carbonator contemplates the use of a cylinder or carbonator body which is constructed of amaterial which in itself is resistant to the action of water, the action of the carbon-dioxide gas, and of the two mixed together.

For the purpose of disclosing my invention, vI have illustrated one embodiment thereof in the accompanying drawings in which;

Fig. 1 is a longitudinal section of a carbonator embodying my invention;

Fig. 2 is a front'elevation partly in section; and

Fig. 3 is a detailed sectional view of the pump used in connection with my carbonator.

In the embodiment of the invention illustrated, I provide a Vertical plate 1 preferably circular in form and having at its lower edges a pair of feet 2 to which are attached 1929. Serial No. 345,696.

anglebars 3 forming the base or support for the entire structure. This plate 1 may be formed of cast iron and provides acover plate for the carbonator body. The carbonator body 4 which may be ycylindrical is secured to one face of the plate 1. To this end the body 4,at its forward end, is provided with an annular flange 5 seating against the face of the plate and having interposed therebetween and the plate a gasket 6 for making a tight seal between the two. The body 4 is secured in positioniby means of a clamping rmg 7 engaging the rear face of the flange 5 and helcl in position on the plate by bolts 8. i This Vcylindricalcarbonator body is formed from a single sheet of metal drawn into cylindrical form and having its interior'highly polished. I have discovered that metal comprlsing a miXture of nickel'7-10%, chromium 18-20%, phosphorus 025%, sulphur 025%, silicon .50%, manganese .50%, carbon .20% and the balance iron is impervious to attack by the water, is also impervious to any destructive effect of the carbon-dioxide gas. Furthermore, I have discovered that even when the water and gas are mixed and agitated, this metal is impervious to attack thereby. In order to render the plate 1 likewise impervious to attack, this plate is coated with a lining of tin as at 9.

The apparatus for supplying the carbonator body with water, including the pump; for supplying` the carbonator with` gas, including the valve and lead ins and the apparatus for controlling the operation of the device are all mounf'ed upon and supported by the plate 1, being mounted on the face of the plate i opposite the carbonator body. For supplying the body with gas and water, I provide a nozzle 10 having a gas discharge openingll formed aXially therein and having extending through this opening, a water spray nozzle 12 whichis screw threaded into the end of the `nozzle Vbody 10 and providedat its inlet end with suitable ports 13. The opposite end of the water nozzle 12 projects beyond the gas nozzle opening 11 and is provided with suitable spray openings 14.

This spray nozzle is surrounded by a hub i 15 having asupply opening 16 and formed on J charge stroke of the piston.

the end of the water inlet pipe 17, the oppolsite end of which is connected to the discharge end of the pump 18. The gas supply nozzple is connected to the supply pipe 19 which is provided on its end with a connection nipp'le 20 adapted to be connected with the gas supply.

The water is supplied to the carbonator through the pipe `17 by means of the pump W 18.

This pump comprises the 'casin'g 21 'which is bolted to a 'supporting plate 22 forming la part of the front plate casting 1, by means of ears 23. The pump is provided with a cylinder 24 in which operates -a pisto1-125,the

piston being adapted to operate through a This cylinder '-24 suitablepacking gland 26. discharges into a head'27 having -a 'dischar'g'e port 28 Controlled by a check Valve 29 and is connected through this valve with the water supply pipe 17. i T his Valve'29 is spring seated by ai, coil spring 30. The head 27 also communicates with the intake side -31`of the pump and this side is provided with a check valve 32. This valve is of the rubber flapper type. I` have foundth'at this type of valve Vis particularly advantag'eous for this class of carbonator. The valve opens rea'dily under the influence of lthe inrush of the water, closes promptly with no noise on the dis- Furthermore, this type of Valve is particularly advantageous in this type of apparatus as the pump is of the high speed type and 'with this pari ticu'lar type of valve, the sli'ppage is reduced to a minimum.

VThe pump is driven from the drive wheel' 33 mounted on a shaft 34. The hub of this wheel is provided with an eccentric 35 which is connected with the pump plunge'r by an eccentric IStrap and the connec'ti'ng rod 36, The drive wheel is keyed on the sh'aft 34 s'o that, the shaft will rotate with the wheel 'and this wheel is driven from an electric'motor 37 mounted 4on a platform 38 supported on the top of the plate 1. This motor is provided with a grooved pulley 39 which is connected by a V type rubber belt '40 Wit-h the drive wheel 33. o

Thisv shaft 34 is mounted in a bearing 41 supported in an oil cup 42 formed integrally with'the plate 22. This cup comprises an oil pack for the shaft so that, the shaft may be run for long periods without re-oiling. The shaft extends through the face plate 1 through a suitable packing gland 43 and has mounted on its inner end within the carbonator body 4 an agitat'ing paddle 44.

The discharge from the carbonator body is from the lower end through a discharge pipe 45 which lies close to the bottom of the carbonator and extends through the front plate 1,'fb'eing connected witha discharge pipe 46,, in turn connected with an outlet nipple 47 .o This pipe is surrounded by a second pipe 48 connected' through a'su'it'able iincide with the pressure in the carbonator.

This -arrangement .permits of the bucket to fill with carbonated water to the samevextent that the ca'rbonator becomes filled. This bucket is supported fromone end of a l'ever 54, supported on a piv'otpin extending from the front plat-e l, and the opp'osite end of the`lever carries fa. vcounter-bala'ncing i weight 56. The bucket and lever a're connected through la suitable lost motion-connector rod 57 with a switch handle 58 of a snap switch V59 adapted to control 'the circuit through the electric motor 37, the 'connection being such that whenthe bucket 52 is in its lowermost position, the circuit through the motor will be opened -and when the -bucket is raised to its' highestV position, the Circuit throughthe motor' willV be closed.

In'operation the `carbon-diolxide gas Vis admit'tcd to the inlet nozzle'through the inlet pipe 19. This gas is delivered from the carbon-di'oxide -container at an ex'tremely high pressure, but'the'pressure is reduc'ed to approximately 100 pounds pressure before it 'passes into the carbonator. At the vsame time water is delivered'through the spray nozzle 'and itis` to be noted that the nozzle arrangenrent 'is s'u'ch that the' spray of water i'ssuin'g into the carbonator is surrounded by a cone of gas Vso that 'the water rapidly absorbs thegas anddue to the rotation of the agitator 44, the gas and water are thoroughly mixed until the water reaches the satiuration point. 'The carbonator gradually fills with the-'carbonated wat`er,unless it is drawn 'off at the same time, and 'during this filling operation, the bucket 52 likewise becomes filled 'with water until by the time the 'desire'd i water level is reached the carbonator, the weight of the water of the buclret 52 will over-balance the carbonator weight 56 causing the b'ucket to drop and operate the switch 59, to shut off the motor. This shutsoffthe pump and 'the operation'offthe machine until sufficient water has been w'ilthdrawn from the carbonator and the bucl'tet to permit the weight of the counter-balancing weight 56 i to Vovercorne theweight of the bucket and th'us start the motor to opierate.v f i 'I 'claim as 'my invention:
